Abstract
A uniformity waveform for a tire (T) and a rotational phase of a load drum () are measured with a load drum () pressed against the tire (T). In a waveform of the frequency domain acquired by frequency conversion of the uniformity waveform, the amplitude and phase for a component of an integer multiple of the rotational frequency of the load drum () are found and stored as a correction parameter. A corrected tire (T) uniformity waveform is calculated by subtracting from the uniformity waveform a correction waveform calculated on the basis of the correction parameter, the correction waveform being the one in the rotational phase range of the load drum () during tire measurement.
